SPRING SEAT.

This invention relates to spring seats for farm machinery, such astractors, wheeled cultivators and the like, and has for its principalobject to provide a means whereby the operator of the machinery mayobtain a maximum comfort occupying the'seat.

Another important object of the invention is to provide a spring seat ofthe above mentioned character wherein means is provicled for limitingthe upward movement of the seat, as well as limiting the downwardmovement thereof.

Another important object of the invention is to provide a spring seat ofthe above mentioned character, which is simple in construction,inexpensive, strong and durable, and further well adapted for thepurposes for which it is designated.

Other objects and advantages of this invention will become apparentduring the course of the following description.

In the accompanying drawing, forming a partof this specification, and inwhich like numerals designate like parts throughout the same:

Figure 1 is a side elevation of the spring seat embodying my invention.

Figure 2 is a top plan View thereof with the seat removed, and

Figure 3 is a sectional View, taken approximately on the line 33 ofFigure 1.

In the drawing, wherein for the purpose of illustration is shown thepreferred embodiment of my invention, thenum-erals 1 and 2 designate apair of vertically spaced horizontally arranged plates, each of which isof substantially rectangular design, the lower plate 2 being adapted tobe secured on the upper end of the seat supporting beam 3 by anysuitable fastening means, such as is shown at l. The upper plate 1 isadapted to be secured on the bottom of the usual seat 5, in any suitablemanner.

Disposed between the spaced upper and lower plates are the helical coilsprings (3. The springs are arranged on each of the sides of the plate,one spring being provided for each of the sides and the same beingarranged centrally, or intermediate the ends, in a manner as moreclearly illustrated in Figures 1 and 3 of the drawing. The helical coilsprings are spaced inwardly from the side edges of the plate and securedat their respective ends to the upper and lower Application filedSeptember 10, 1924. Serial No. 786,903.

secured thereto. bumpers, such as are shown at 8, are arranged at thecorners of the lower plate 2, and extend upwardly for a' suitabledistance, in the manner as more clearly illustrated in Figure 1.

In order to prevent any sidewise move ment of the upper plate and seatsecured thereto, with respect to the lower plate 2, the diagonallyarranged coil springs9 and 10 are secured at their lower ends to theplate 1, as at 11, while the upper ends of the diagonally extending coilsprings are secured to the upper plate 1, on opposite sides of each ofthe corners thereof.

It is off 'course to be understood that the diagonally arranged coilsprings are arranged at each of the corners of the plate, in the manneras shown in the drawing.

The provision of a spring seat of the above mentioned character, for usein connection with tarm' machinery, will enable the operator of themachinery to be seated comfortably thereon. all times be positive andefiicient in their operation.

While I have shown the preferred em- The springs will at' bodiment of myinvention, it is to be understood that various changes in the size,

shapes, and arrangementof parts may be resorted to without departingfrom the spirit of the invention or the scope of the claim.

Having thus described my invention, what I claim as new is:

In a spring seat structure, a pair of vertically spaced horizontallydisposed plates,

spring means holding said plates normally ture;
